Potassium Essays

order to test if Potassium reversal potential is a good predictor of membrane potential. We predicted that even though there are many ions in and around a cell, reversal potassium of Potassium will give a good estimate of the membrane potential. In order to test our hypothesis, we measured the membrane potential across crayfish muscle fibers that were submerged in different saline solutions containing varied potassium concentrations. We also calculated the reversal potential of Potassium for those concentrations

The Element Potassium The element Potassium was discovered in 1807 by a chemist named Humphry Davy. Potassium was named after the English word “potash”, originally meaning an alkali extracted with water in a pot of burned wood and ashes of plants. Metallic potassium was first isolated by Humphry in 1807 through the electrolysis of molten caustic potash in which potassium was the first isolated metal. The symbol “K” comes from the Latin word meaning kalium and this element is not found in nature

Hyperkalemia What is hyperkalemia? Hyperkalemia is the medical term for high serum potassium levels. This is often caused by kidney disease, high dietary potassium intake, increased cell breakdown, insulin insufficiency, and use of certain medications (eg, NSAIDs, beta-blockers). Rapid elevations in potassium or very high potassium levels may produce symptoms such as muscle weakness, paralysis, cardiac arrhythmias, and even death. Hyperkalemia that does not respond to medical therapy may require

sodium and potassium in the ICF and ECF According to Hale & Hovey, 2014, intracellular fluid is liquid that is found in the cells and it makes up around 60% of fluids present in the body. The fluids found outside the cells are extracellular fluids, and they make up the remaining percentage of body fluids. Sodium ions are the major cations present in the extracellular fluids while the potassium ion is the key cation in intracellular fluids. The concentration of the sodium and potassium cations contrast

potential, which is essentially the flow of ions in and out of the neuron that differ from the normal flow, one must understand the relation of ions, especially sodium and potassium, with the neuron. Neurons are covered by membranes that regulate the inflow and outflow of chemicals, and certain chemicals, like sodium and potassium can only flow in and out via channels along the membrane. At rest, the membrane maintains a certain polarization between the inside and outside of the neuron, with the inside

Flame Tests of the Elements Lab 1. According to your observations, which metal ion is present in your unknown samples? Explain your rationale. According to the observations recorded, the metal ion Cesium is present in the “unknown samples”. Unknown sample number five produced a violet color when placed in the flame. Unknown sample number four produced an orange color when placed in the flame. Unknown sample number one produced a violet color when placed in the flame. This evidence supports the claim

the purpose was to identify the cation in an unknown substance based on its characteristic color in a flame. Each color is represented by the amount of photons being released by the compound’s electrons. The first compound tested was Potassium Chloride. Potassium Chloride has a slightly pink and purple color due to the salt which produces it. The next substance examined was Sodium Chloride which appeared to be orange because sodium is placed within a blue flame. The flame raises the electron causing

temporarily changed (Berndt et al., 2011) Sodium ions are actively transported out of the axon, of the neuron, and potassium ions are actively transported in. This is performed by the sodium-potassium pump. This establishes a potential difference of charge between the inside and the outside of the axon (both molecules are positively charged but the movement of sodium ions is greater to that of potassium 3:2). The required resting potential

reliably as table salt, that is just bit of the photo. The other part is that an impressive number people don't eat enough potassium in their eating strategies. Put in a more liberal manner, an impressive number people deplete twice as much as sodium, or more, than their bodies require while gobbling up half as much potassium that they require, or less. The affirmation of potassium to sodium ought to be a degree of around 3:1. For large number individuals, it is more like 1:3; the switch. Surrounding

The results from most of the experiment best fit with Potassium chloride, although not all the test fit with potassium chloride. For example, in “Part A” When the salt was put in the flame it made the flame turn violet. This supports the conclusion that the salt is potassium chloride because potassium chloride also makes a violet flame when burned. The flame test was the most conclusive test because all 8 of the possible salts that were given have very significant flame color. None of the other salts

metal component of the compound. The non-metal element that was in the compound did not mater. Compounds with Lithium (Li) were always red, compounds with Sodium (Na) were always yellow, compounds with Calcium (Ca) were always orange, Compounds with potassium (K) were always lilac, and compounds with Copper (Cu) were green. Going down the group there would be higher energy, which is shown through the visible color of the flame produced. It is shown in the graph how the energy of each wavelength in photon

sodium, potassium, magnesium, and calcium can help retain fluids, and proper fluid balance contributes to optimal performance. Sodium is the most important electrolyte to monitor during exercise or play. High losses of sodium, typically through sweat, can lead to muscle cramps, which can lead to decreased performance and possibly more major health complications. Sodium losses in sweat are greater than any other electrolyte. Potassium, along with sodium helps prevent muscle cramps. Potassium is present

exceed $1.5 billion a year” (Skerrett). And yet, sports drinks are made up of just water, salts, and sugary additives. These salts are known as electrolytes, and are the key characteristic of sports drinks. Examples of electrolytes include sodium and potassium, which can be found in sweat (Smolin). As athletes sweat they lose these electrolytes that play an important role in the body’s functions; they prevent muscle cramping and help nerves transmit impulses, along with also transporting fluids across

Aluminum The word aluminum comes from the Latin word “alumen” meaning “alum”. Aluminum was discovered in Denmark in the year of 1825. Alum was used by the Greek and Romans for medicine as an astringent, and dyeing processes. Aluminum is a chemical element that is located in the boron group. Aluminum’s chemical symbol is Al, and its atomic number is 13. The chemical is a silvery- white, nonmagnetic, ductile metal, that is used all throughout the universe. It’s also the third most abundant element

cation is the cause of the color change is because when I observed the flame color created by the different salts, there some a couple of similarities and differences that I found in each chemical formula. Two formulas that I were drawn to first were potassium chloride and sodium chloride. They both have the same anions however they have different cations and this is the first clue that I found to try to find out which ion causes the flame color change. The next clue that I found that the anion wasn’t

Question One: A. When you eat a Hungry Jack’s Ultimate Double Whopper you consume about ⅓ of daily recommended intake in kilojoules and 4/7 of fat. Now imagine adding 4 pieces of chicken nuggets, large french fries, soft drink and a caramel sundae. That’s about a whole day’s worth of energy and nutrients squashed into one meal. In Isaac’s case, an aftermath of eating a horrible days intake in one meal, he is unable to burn enough kilojoules to counter the accumulation of fat and sugar which is stored

Proteins play a very important role in the human body. Our everyday lives are dependent on proteins functioning correctly. The human body contains many many proteins that must all work together perfectly or problems can occur. There are several different types of proteins also in the human body, but the one being focused on will be the Calcium Pump protein, which is located in mainly muscle cells (Klabunde, 2010). The calcium pump works by pumping calcium out of the cell (Klabunde, 2010). It

Is Sodium Taking Over Your Health? Did you know that we are eating way too much sodium, in lots of foods that you wouldn’t be expecting it in? Have you ever looked at a label, specifically at the sodium label? Sodium also could be referred to as “The Silent Killer” because not many people know the causes of eating sodium.Sodium has a lot of side effects on eating to much of it, such as fluid retention in the body heart, high blood pressure, and dehydration. This research paper

The main aim for the campaign ‘Adults and children over 11 should eat no more than 6g of salt a day’ was to inform and raise awareness of salt as a public health issue. The recommendation came about by The UK’s Committee on Medical aspects of Food and Nutrition Policy in 1994 and further validated in 2003 by the Scientific Advisory Committee on Nutrition. A number of research that have been carried out showed that a high salt consumption is the key reason as to why elevated blood pressure occurs
